今天脚本总报timeout的错误，timeout的异常处理是什么啊？
下面的try except没用

        try:
            url_open = urllib.request.urlopen(url)
        except urllib.error.HTTPError:
            print('HTTPError')
            continue
        except urllib.error.URLError:
            print('URLError')
            continue

就是返回

  File "F:\Program Files (x86)\Anaconda3\lib\http\client.py", line 612, in _safe_read
    chunk = self.fp.read(min(amt, MAXAMOUNT))
  File "F:\Program Files (x86)\Anaconda3\lib\socket.py", line 586, in readinto
    return self._sock.recv_into(b)
   timeout: timed out

把except写成

except Exception：

也没用
